Considering exhibition in modern society as a huge and complex medium, I attempt to develop useful information models and possible ways of organizing information resources from the perspective of the general public who accept it.

  This paper, I report a result of the trial of a structured description, based on an existing common vocabulary/ontology, for a wide range of the information which is produced, distributed, and received related to the exhibition. For the structured description, I adopted the model which I presented in the previous issue of this journal for the target information items, and applied CIDOC CRM, which domains museum information, as the common vocabulary/ontology. In this case, the various considerations regarding semantic interpretation occurred in realizing structured descriptions, and I attempted to organize those comprehensively in a visual format, and positioned it as an auxiliary reference model.

  With the above as a prerequisite, the conclusion is that it is possible in considerable degree, to describe the various information distributed at an exhibition in a structured manner using CIDOC CRM. In addition, by applying object-oriented extensions suggested by CIDOC CRM itself, it is possible to gain the comprehensiveness and refinement of the description.

  This article examines records of exhibitions of the Japanese collection of Felix Tikotin, a Jewish art dealer, during his stay in the Netherlands（1933–1960）, to ascertain Tikotinʼs activities and achievements there. First, a list of exhibitions including his Japanese collection was compiled by examining Dutch digital archives; second, the respective exhibition catalogues were checked as far as possible. In summary, the Tikotin Japanese Collection exhibited in the Netherlands was often the first presented in Europe or the Netherlands, or the first major exhibition on the subject, and was a leading force in the reception of Japanese art in the Netherlands.

  Since 2015, at the Faculty of Music, Tokyo University of the Arts, we have conducting a systematic investigation of student mobilization at the former Tokyo Academy of Music. We also have held concerts of compositions by students who died in World War II, and are building a digital archive of recordings along with their manuscripts. The purpose of this report is to examine a series of activities and clarify the significance, validity, and challenges of passing on their manuscripts and sound sources to future generations.

  Yamagata International Documentary Film Festival has been held every other year since 1989, and has the Yamagata Documentary Film Library which collects, preserves, and gives access to the past entries of the festival, including award winning titles. The author, who has been assigned to conduct a survey of the library collection, had the opportunity to visit its sister organization, the Northeast India AV Archive. This newly established archive in India, a country with a rapidly growing economy, is aiming to protect the cultural identity of the Northeast, while the veteran library in Yamagata opened in the 1990s when motion picture film was still the mainstream medium. Both are crucial institutions for each region, and the exchange between the old and new has mutually beneficial significance.

  Recent trends in establishing new libraries have included a shift in the information environment, marked by the integration of multifunctional facilities. In addition to the physical resources traditionally managed by libraries, there is now a growing need to provide access to digital information, including digital cultural heritage. The authors conducted a workshop using a participatory design method in human-centered design to derive information useful for defining the requirements of a digital archive that offers an excellent user experience（UX）, particularly in the field of citizen-participatory regional archives. Analysis of the data obtained from the workshop confirmed the need to design mechanisms for cultural heritage preservation within the community by incorporating digital archives as a key component.

  Since its opening, the Hokkaido Museum of Northern Peoples has used commercially available database software to build a database of its collection for its operations. In the spread of the new coronavirus, the museum sought to increase the number of users to the museum without having to come to the museum and decided to start publishing information on the museumʼs collection on the Internet, which had been a long-standing concern.

  In the course of researching the release of museum collection materials, it came to be considered essential to use IIIF for images, and Omeka S, a content management system dedicated to digital archives, was adopted to perform this task.

  In this case report, we introduce a case study of the construction of a database of museum collection materials using Omeka S.
